Photos by bertiegregory | A fin whale passes by off Elephant Island in Antarctica. These giants can grow to more than 80 feet (25 m) in length and weigh about the same as 16 African elephants! In the underwater image, the whale has just taken in an enormous mouthful of the sea, using both the elasticity of its mouth and its giant tongue to push the water back out through hairlike plates called baleen. This filtering system catches its krill prey. Filmed for Epic Adventures, now streaming on disneyplus. #EpicAdventures #EpicAdventuresWithBertieBregory
